Climate change is caused by the increasing emissions of 'greenhouse' gases from human activity. Predictions indicate that climate change could seriously affect the climate of the UK and of London and could impact many areas of life.

The London Climate Change Partnership's report 'London's Warming' gives stark predictions:

• Extreme weather is likely to become more frequent and more intense, with wetter winters, hotter and drier summers, prolonged heat and increased wind intensity.
• The risk of flooding could increase from increased intensity of rainstorms, more frequent intense winter rainfall and by raising sea levels and potentially increasing winter storminess - leading to more frequent closures of the Thames Barrier.
• London is warmer at its centre than at its edges – the urban heat island effect. Increases in summer heat island intensity and frequency are expected to occur, reducing comfort in the city’s buildings and transport network and increasing summer electricity demand. By the 2080s, London’s summer extreme temperatures could be comparable with those of present-day New York.
• London is one of the driest capital cities in the world, with available water resources per head of population similar to that of Israel. Climate change could reduce the amount of water available and increase demand in summer and increasing the risk of drought.
• Climate change is expected to affect investments both in the UK and abroad, impacting on London’s Stock exchange and the UK economy.
• Climate change could present some important opportunities for London. For example, tourism and recreational industries could benefit considerably. It may also offer new opportunities for the financial sector.

The Greater London Authority, Government and London boroughs are working to reduce emissions of 'greenhouse' gases and promote the use of renewable energy and more energy efficient building design.
